(Nanowerk News) In many respects, metamaterials are supernatural. These manmade materials, with their intricately designed structures, bend electromagnetic waves in ways that are impossible for ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

A microlens that uses negative refraction to achieve a record focal length of 12 µm could benefit high-density imaging and optoelectronics systems. US researchers have engineered a concave photonic ...

When light moves from air into glass or plastic it is refracted close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ...

There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

X‐ray optics has emerged as a critical field in modern imaging and fabrication, utilising refractive lenses that enable the precise control and focusing of X‐ray beams. Refractive lenses, particularly ...
